Title: Disk record reproducing device
Inventor: SUZUKI MICHIO
IPC: G11B7/085
Filed: 1982-10-08
Abstract: PURPOSE:To prevent a spot from being shifted when starting movement even if a tracking servo is stopped at the time of movement of a pickup, by holding an output signal from a tracking servo circuit at the time of stop of the tracking servo, and fixing a converging lens. CONSTITUTION:A sample holding circuit 21 leads a tracking servo signal to a pickup 13 as it is in case of a regular reproducing state, and performs a tracking servo. When a search operation is requested, a controlling circuit 22 outputs a control signal for requesting a holding state to the sample holding circuit 21, and the sample holding circuit 21 holds a tracking servo signal which is outputted immediately before the control signal is supplied. Therefore, a converging lens of the pickup 13 is fixed, and in this state, movement of the pickup 13 is executed. Subsequently, when the pickup 13 reaches an object position, the controlling circuit 22 stops generation of the control signal, releases a holding state of the sample holding circuit 21, and the tracking servo is started immediately at the objective position.

Abstract: PURPOSE:To stabilize switchingly a power supply having a capacitive component by providing a means discharging quickly an electric charge stored in the capacitive component of a load side when a voltage in response to the changeover of a detector and an output voltage have a prescribed relation. CONSTITUTION:When an output voltage drops a load voltage from V2 to V1 by the switching of a switch 22 for a thermister 1, it is required to discharge the electric charge of a capacitor 31. To an input of a comparator (COMP) in a discharge control circuit 23, a voltage Vc detected by a thermister switched by the switch 22 and an output voltage Vd of a DC/DC converter are applied. When Vc<Vd, the level of an output Vf of the COMP is low to turn on a transistor (TR)Q1. A current flows to the capacitor 31 by the operation of a resistor R7 in the path of ground-TRQ1-R7-capacitor 31 until the relation of Vc=Vd is obtained, and the electric charge in the capacitor 31 is discharged from the switching of the thermister until the load side voltage is stabilized in a shorter stable time.

Filed: 1990-07-06
Abstract: PURPOSE:To increase electrostatic breakdown strength, by forming an I/O protecting circuit by using a FET having a gate insulating film thicker than that of a FET driven by a power supply system for ordinary operation use. CONSTITUTION:The thickness (y) of a gate insulating film 15a between a first semiconductor polycrystalline layer 14a and a substrate 1 is thick and, e.g. about 450Angstrom  which is similar to the film thickness of a FET for high breakdown strength use. Hence, in the range of power supply voltage at the time of ordinary operation, the decrease of reliability that the threshold voltage increases and the current decreases can be restrained, without adopting an LDD structure. The impurity concentrations of the source region 2a and the drain region 2a of the FET are high and, e.g. about 1X10<20>cm<-3>. As the result, resistances of both regions 2a become low, and heat inducing junction breakdown is not generated in both regions 2a when an excess voltage is applied to an input terminal 13.
